From the video.
The runway can handle three to four times the traffic of a normal runway.
You can alter the approach on extremely windy days.
You can also alter the approach to avoid only one approach area having to bear the brunt of the noise all the time.
I’m not sold on it, but some of the benefits seem reasoned.
It really can’t handle 3 or 4 times the traffic, the guy is just making crap up. Because you simply do not EVER want multiple planes getting up to speed (or down) on the same piece of tarmac at the same time. Somebody’s speed will vary and it’ll all go to crap.
On a windy day you eventually are going cross wind if you’re in a circle, so altering the approach accomplishes nothing. Straight runway systems always have one perpendicular to the rest, which is the correct way to alter for wind.
Approach area noise is a small problem.
It is, simply, a terrible idea. It has no benefits, and dozens of serious problems. None of the benefits he lists are reasoned at all, he’s an idiot.
